Abstract

The invention relates to an axle counting method and an axle counting system based on wheel-rail coupling shear force detection. The axle counting method comprises the following steps of measuring and acquiring deformation data at a steel rail measuring point in real time; obtaining a wheel-rail coupling shear force curve at the measuring point according to the deformation data; obtaining a strain difference curve according to the wheel-rail coupling shear force curve; and performing axle counting according to the strain difference curve; the axle counting system comprises a plurality of fiber bragg grating sensing elements, an elastic substrate and a calculation unit, wherein the elastic substrate is used for fixing the fiber bragg grating sensing elements; the fiber grating sensitive element is used for measuring and acquiring deformation data at a steel rail measuring point; and the calculation unit is used for receiving the deformation data from the fiber grating sensing element, obtaining a wheel-rail coupling shear force curve according to the deformation data, obtaining a strain difference curve according to the wheel-rail coupling shear force curve, and finally performing axle counting according to the strain difference curve.

Description

technical field [0001] The invention belongs to the technical field of train detection, and in particular relates to an axle counting method and an axle counting system based on wheel-rail coupled shear force detection. Background technique [0002] With the continuous development of science and technology, axle counting devices have been widely used in rail transit signal systems under different engineering environments and line conditions, and there are many application schemes. At present, the axle counting schemes in the railway system mainly include electromagnetic axle counting schemes. [0003] Electromagnetic induction axle counting is to use, when there is a train passing by the axle counting point, the wheel axle cuts the magnetic induction line to cause the induced electromotive force on the induction coil, which is compared with the change of the induced electromotive force when there is no wheel, so as to judge whether there is a train passing by to realize the ...
